I'm not impressed --- the list of unsolved problems is a bit too long.
One that seems a showstopper for our purposes is lack of ability to
deal reliably with stack overflow on alternate stacks. If we're going
to be doing anything as loosely defined as running a third-party
language interpreter in these stacks, that just won't do.
Another little problem is it's LGPL.
